Abstract

In this paper, we sampling surveyed on the Artemisia ordosica population under different habitats (include artificial vegetation area established from 1964 and natural vegetation area) in southeastern edge of the Tengger Desert. The A.ordosica population was divided into seven age-class according to the volume level. We analyzed the composition of population, static life table and survival curve. We developed the following conclusions:(1) The overall size of the A.ordosica population in artificial vegetation area is larger than in natural vegetation area. High proportion of A.ordosica population is young individuals in two habitats. (2) The death rate of A.ordosica population in natural vegetation area is lower than in artificial vegetation area. The age-class Ⅰ and Ⅱ of A.ordosica population in natural vegetation area have the highest death rate and the age-class from Ⅴ to Ⅶ in artificial vegetation area have the highest death rate. (3) The stability maintenance of A.ordosica population in natural vegetation area is mainly through seedling regeneration. In artificial vegetation area, the stability maintenance through seedling regeneration and self-thinning effect of older individuals. (4) The age-class Ⅴ of the A.ordosica individuals have best quality of life in population. (5) The population survival curves in different two habitats were close to Deevey-Ⅱtype.
